DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-2 , Figure 4 As shown, the concrete door leaf curing device for the civil air defense door provided by the utility model includes: a support mechanism 100 and a spraying mechanism 200, the spraying mechanism 200 is installed on the support mechanism 100, the main function of the support mechanism 100 is to support the door panel 300 of the civil air defense door, and the function of the spraying mechanism 200 is to spray water onto the door panel 300 for curing concrete. Specifically, the support mechanism 100 includes a vertical plate 101, which is a weighing structure of the entire device for transferring loads. Its structure is as shown in FIG. Figure 2 As shown in FIG, a support frame 102 is horizontally provided on one side of the middle of the vertical plate 101, and a door panel 300 is placed on the upper end of the support frame 102. Figure 1 As shown, the door panel 300 is heavy, and the concrete after initial setting has a certain strength. At this time, the door panel 300 can be transferred to the support frame 102 of the maintenance device by means of a forklift. The spraying mechanism 200 includes a water pipe 201, which is arranged above and below the support frame 102. The water pipe 201 is provided with a nozzle 202, and the nozzle 202 can rotate, such as Figure 4 The structure of the rotatable nozzle 202 is shown, which uses the momentum of the water flow to achieve the effect of pushing the nozzle 202 to rotate. The specific structure includes: a connecting pipe 208 fixedly sleeved in the water pipe 201, where the water pipe 201 is the outer convex part perpendicular to the water pipe 201 pipeline, a rotating cylinder 207 is sleeved in the connecting pipe 208, and the connecting pipe 208 is slidably connected to the rotating cylinder 207. The outer walls of the upper and lower ends of the rotating cylinder 207 are respectively provided with a second baffle 209 and a first baffle 205. The upper end of the rotating cylinder 207 is connected to a curved pipe 211, and a nozzle 210 is provided on the surface of the curved pipe 211. The nozzle 210 is inclined upward, and the water enters the rotating cylinder 207 from the water pipe 201, and finally sprays out from the nozzle 210 on the curved pipe 211. The water jet generates a reverse driving force on the curved pipe 211 to rotate the curved pipe 211.

[0027] By arranging water pipes 201 and nozzles 202 at the upper and lower ends of the door panel 300, the watering curing effect of the concrete slab is achieved. Compared with the prior art, the water pipes 201 located above and below the door panel 300 can simultaneously perform watering curing on the concrete, that is, the upper and lower surfaces of the concrete can be fully in contact with water, thereby avoiding insufficient curing of the concrete slab and ensuring the structural strength of the concrete.

[0028] By providing a rotatable spray head 202 , the water can be sprayed more evenly during the sprinkling and curing of concrete, and the coverage area of ​​the sprayed water is larger, which is conducive to fully spraying the water on the surface of the door panel 300 .

[0029] Second embodiment:

[0030] like Figure 2 As shown, the support mechanism 100 also includes a lifting member 103, which is a vertical traction device, such as a rail-type hydraulic lift. The lifting member 103 is slidably installed on one side of the vertical plate 101, and the support frame 102 is fixedly connected to the lifting member 103. When the lifting member 103 moves up and down, it can drive the support frame 102 to move up and down synchronously, thereby driving the door panel 300 thereon to move up and down.

[0031] In actual working process, the specifications of door panels 300 are not uniform, and they are designed according to the actual use requirements of the building. Therefore, larger door panels 300 cannot be transported by forklift, and generally a flatbed truck is used for auxiliary transportation. The height of the flatbed truck is fixed. At this time, the height of the support frame 102 can be adjusted by the lifting member 103 to adapt it to the height of the flatbed truck, thereby facilitating the staff to push the door panel 300 horizontally onto the support frame 102.

[0032] Third embodiment:

[0033] like Figure 2 As shown, a water collecting tank 204 is provided on one side of the vertical plate 101, and the water collecting tank 204 is located at the lower end of the support frame 102. The water sprayed by the water pipe 201 located below will flow downward under the action of gravity after reaching the lower surface of the door panel 300. The water collecting tank 204 can collect the flowing water for reuse, while reducing the pollution of the environment caused by the water flowing to the ground.

[0034] Fourth embodiment:

[0035] like Figure 5As shown, a supporting frame 104 is fixedly installed on one side of the vertical plate 101, and a mesh 105 is provided on the upper end of the supporting frame 104. A water-storage cotton cloth is placed on the upper end of the mesh 105. The mesh 105 plays the role of supporting the water-storage cotton cloth. After the water pipe 201 at the lower end sprays water, it will drip downward under the influence of gravity. Compared with the water at the upper end of the door panel 300, the retention time is shorter, resulting in an incomplete hydration reaction of the concrete. Therefore, the water pipe 201 at the lower end of the door panel 300 can spray water onto the water-storage cotton cloth on the mesh 105, and then the door panel 300 on the support frame 102 is driven by the lifting member 103 to move downward to the white surface of the water-storage cotton cloth, and the upper end of the water-storage cotton cloth contacts the concrete surface of the door panel 300. A certain amount of water can be stored in the water-storage cotton cloth for sufficient hydration of the concrete at the lower end of the door panel 300.

[0036] Fifth embodiment:

[0037] As shown in the figure, one end of the water pipe 201 is installed on the water pump 203, and a water inlet 206 is also installed on the water pump 203. The other end of the water inlet 206 extends to the bottom of the water collecting pool 204. After the water pipe 201 located at the lower end of the door panel 300 sprays water to the lower end of the door panel 300, the water will drip downward. The dripping water is collected by the water collecting pool 204, and then extracted through the water inlet 206 under the action of the water pump 203 and re-sprayed onto the door panel 300 for use. When the amount of water in the water collecting pool 204 is insufficient, it will be supplemented from the outside.

[0038] When in use, first use a forklift or flatbed truck to transfer the door panel 300 to the support frame 102, then start the water pump 203 to spray the water in the water collection tank 204 through the water pipe 201 and the nozzle 202. The upper and lower ends of the door panel 300 are both black with water pipes 201 and installed with nozzles 202. Water can be sprayed out from the water pipes 201 at the upper and lower ends at the same time to spray and moisten the concrete of the door panel 300.

[0039] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
